The cost price of a shirt is ₹450. A shopkeeper marks its price in such a way that he earns a profit of 24% after giving 25% discount on its marked price. The marked price (in ₹) of the shirt is:

We can use the direct relation formula between Cost Price (CP) and Marked Price (MP):
CP
MP
​
=
100−Discount %
100+Profit %
​

Given:

CP=₹450

Profit %=24%

Discount %=25%

Substitute the values:

450
MP
​
=
100−25
100+24
​

450
MP
​
=
75
124
​

MP=450×
75
124
​

MP=6×124=744
Thus, the marked price of the shirt is ₹744.
